PSCH is used to transmit trip signals. On the other side of the line the RREC decides if he wants to reclose the tripped CB.
For me it is not clear, for what mechanism, an TxEnaAutoRec shall be used. May be the breaker failure function has some impact? Please explain the protection scheme with transmission of disabling of RREC.
